Annual Report 2012 - Knorr-Bremse AG.

Report
113
The modern HVAC systems feature two separate cooling circuits filled with R-134a refrigerant. The
units have a maximum cooling output of 35 kW, and a maximum heating output of 32 kW. During
operation a sensor constantly monitors the CO 2
content of the air in the respective compartment. The
higher this rises, the more fresh air the system draws in from the outside.
Knorr-Bremse receives follow-up order for Velaro RUS 2
Sapsan – meaning peregrine falcon – is the name given to the Velaro RUS high-speed train manufactured
by Siemens. Russian state railway operators RZD use their eight Sapsans on the busy
line between Moscow and St. Petersburg, amongst other routes. Despite making a number of
halts, the high-speed trains cover the 650-odd kilometers in a mere 3 hours and 45 minutes. And
even in challenging weather conditions the Sapsan achieves reliability levels of between 95% and
98% – thanks partly to the braking, HVAC and door systems developed and supplied by Knorr-
Bremse.
The Sapsan is to
continue to rely
on Knorr-Bremse
systems for its
journeys from
Moscow to
St. Petersburg.
RZD recently ordered eight more high-speed trains, and Knorr-Bremse will also be supplying the
braking, HVAC and door systems for these new Velaro RUS 2 vehicles. They will be used to increase
the frequency of the service on the busy route between Moscow and St. Petersburg and also on the
line between Moscow and Nizhny Novgorod.
As the power supply on the lines to St. Petersburg and Nizhny Novgorod use different systems, and
RZD wishes to be able to use the trains flexibly on either route, the Velaro RUS 2 had to be capable
of operating in double traction. This meant Knorr-Bremse had to design completely new software
architecture for the brake control system. During the year under review the first of the new braking
systems were delivered to Siemens.
Moscow Metro opts once again for Knorr-Bremse
More than 9 million passengers used the metro system in Moscow at peak periods, and train frequency
is therefore very high. From the point of view of the operator, the vehicles therefore have to be
completely reliable. But there is a further factor – some of the metro runs overground, and the trains
and their systems therefore also have to operate at extremely low temperatures.
Knorr-Bremse’s extensive experience of the Russian market means the company can meet both these
requirements – which was one of the reasons it was chosen last year to supply various systems for the
360 new-generation cars ordered by Moscow Metro from Russian vehicle builders Metrowagonmash
and OAO TVZ. Knorr-Bremse will be delivering oil-free compressors and block brake units. But the
company’s involvement does not stop there – the door systems will be coming from IFE, and Italian
subsidiary Microelettrica Scientifica will for the first time be supplying resistors and circuit breakers.
This has enabled Knorr-Bremse to successfully expand its share of the systems supplied to the metro.
Crucial factors in winning this order were the high levels of service competence demonstrated
by Knorr-Bremse’s local staff and the company’s plan to produce the braking systems directly in Russia.
NYAB strengthens market position in driver assistant systems
In fiscal 2012, Knorr-Bremse’s US subsidiary New York Air Brake (NYAB) continued to expand the installed
fleet for its LEADER driver assistant system. By year’s end NYAB had delivered more than 2,500
systems to eight customers worldwide.
LEADER is a sophisticated train management system that significantly improves the locomotive
engineer’s ability to handle heavy freight trains more economically and safely than ever before.
